Re: Bench test a starter solenoid??
if you jumped the starter and nothing happened and you do in fact have 12.9 volts, you have a bad starter, but it sounds like you have other issues not related to the starter, what is the voltage at the solenoid when you turn the key? does it drop or stay the same? did you check fuses/breakers? you could take out the starter and bench test it but just because it works on a bench doesnt mean it a good starter, it needs to be under a load.
